2011 ACM Awards Performance Pictures

These live shots from the 2011 ACM Awards chronicle all the performances from the show. Many country stars found themselves collaborating with other musicians -- for example, Carrie Underwood teamed up with Aerosmith frontman Steven Tyler, and Brad Paisley joined forces with Alabama. Many stars also performed with elaborate sets, like Taylor Swift's rendition of 'Mean,' which featured a set change from a country home to a big, lit-up city. On the other hand, many singers took the traditional route when it came to singing it out, like Ronnie Dunn, Sara Evans, and Martina McBride.
